A fantastic and easy recipe for celery soup. Celery, carrots and onion are boiled together in chicken stock, thickened and passed through a sieve before serving. You can also blitz the soup with the vegetables, if you prefer.

Carrots give a slightly sweet edge to this thick, smooth soup, which contains delicious pockets of melted blue cheese. All you need with it is some crusty bread to make a satisfying and nutritious main course.
